The high power, energy and safety features allow the NANO cells to be flexibly applied in various applications. But have a closer look at the numbers: This time, current was stable splb 20mA 0.

Notify me of follow-up comments by email. A thermal runaway event is significantly less likely to occur in LTO cells. I divided currents by 4 and 8 so that we can see some detail.

A key factor in maintaining optimum performance is to keep the cell temperature within the designed range. But also new hardware for the electronic load, so testing conditions have improved.

Silverclean design by Iceable Themes. Large High Power cells are the genuine Kokam products with amazing absolute power supply values. Voltage stayed within mV to mV, which is another 0. This time, current is pretty steady, but the voltage looks like it is jumping around a lot.

So unless they have a very weird wiring order, having the 1 cell gassing a lot and the others not doing a thing is a tad strange.

During more than 16 years of Lithium polymer battery manufacturing experience, Kokam has brought a variety of cells to the market and range in size from 3. This feature enables the user to operate the battery cells under extreme environmental and operational conditions.

Kokam produces large scale of Lithium-polymer cells. We use cookies to ensure that we give you the best experience on our website. I never made it to stop the tests before the hard 3. Notify me of new posts by email. UL for all types of cells.

Below shows the additional surface area and much shorter distance that heat must travel to exit the Kokam pouch cells, as compared to a similar capacity cylindrical cell.

So overall stability increased by a factor of 3!


It also looks like the pack is dying cycle over cycle. Proudly powered by WordPress.

The heat dissipation is also correlated with safety. With no memory efect they have singnificantly longer lifetime than lead acid, gel based or Nickel based NiCd, NiMH batteries usually used in these devices.


It might be gassing cells, but I found the weakest cell is actually 3. LTO cells can also be re-operated okkam an event of an over-discharge, unlike conventional graphite based Li-Ion cells.

Thanks to this feature the cells add minimum weight to any portable device. It is clearly aimed at RC stuff, having mAh at 30C discharge rate, I ran another test at 8 amps, which is shown in the graph above.

Home Wan Hung Lo? Large High Energy Density cells with capacities from 20 Ah upto Ah are the genuine Kokam products with the maximum energy density per kilogram on the market.
